Restore Your Vehicle’s Fuel Delivery and Performance
Are you battling frustrating issues like your engine stalling, refusing to start, or hesitating under acceleration? Before you condemn the fuel pump, the real problem is often the Fuel System Control Module (FSCM). As a technician with over 20 years of experience, I’ve seen countless vehicle owners and even professional shops misdiagnose this critical component. This FSCM is the brain behind your fuel pump, regulating voltage to ensure precise fuel pressure for optimal engine performance and efficiency.
This isn’t just a replacement part; it’s a complete solution. We take the hassle and expense out of the repair by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN). When it arrives, it’s loaded with the latest GM factory software, ensuring seamless communication and performance. You get to skip the costly trip to the dealership for programming—this module is ready for installation right out of the box.
I remember a 2011 Silverado 1500 that came into my shop. The owner was at his wit’s end. He had already replaced the in-tank fuel pump twice, but the truck would still randomly stall at red lights and had a long, sputtering crank. The codes were intermittent. We put it on the lift and immediately saw the original FSCM bolted to the frame rail, caked in years of road salt and grime. A quick voltage test confirmed our suspicion: the module was failing under load, starving the brand-new pump of the power it needed. We installed a new VIN-programmed module, and the truck ran like new. It’s a classic case where throwing the most obvious part at the problem isn’t the solution.
Is Your GM Vehicle Showing These Signs?
- ✔ Engine cranks but won’t start
- ✔ Stalling, especially when coming to a stop or under load
- ✔ Noticeable hesitation or stumbling during acceleration
- ✔ Reduced engine power and poor fuel economy
- ✔ Check Engine Light (CEL) with codes like P069E, U0109, or P0230
- ✔ A fuel pump that seems to have failed prematurely
A Straightforward Guide to Installation
Replacing your 2010 VUE Fuel System Control Module is a manageable job for a confident DIYer. While the exact location varies by model (check your service manual), the process is generally similar.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the Module: On many trucks and SUVs (like the Silverado, Tahoe, Yukon), it’s on the driver’s side frame rail, near the spare tire. On cars and crossovers (like the VUE, Acadia, CTS), it may be in the rear compartment, trunk area, or on a crossmember.
- Disconnect and Remove: Carefully unplug the electrical connectors. Be gentle with the locking tabs, as they can become brittle. Then, unbolt the old module from its mounting location.
- Install the New Module: Bolt the new, pre-programmed FSCM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Final Steps: Reconnect the negative battery terminal. Turn the key to the ‘On’ position for 10 seconds to allow the system to initialize before starting the engine. Clear any old trouble codes with a scanner.

Frequently Asked Questions
Frequently Asked Questions
Why do you need my VIN?
Your VIN is essential for us to load the correct, vehicle-specific software from GM onto the module. This ensures it communicates perfectly with your vehicle’s other computers, like the ECM and BCM, for a true plug-and-play installation without needing a trip to the dealer.
What does the Fuel System Control Module (FSCM) do?
The FSCM acts as a smart relay for your fuel pump. It receives commands from the Engine Control Module (ECM) and precisely regulates the voltage sent to the fuel pump. This provides the exact amount of fuel needed for any given driving condition, improving efficiency and performance.
Can I install this myself?
Yes, for many DIY enthusiasts with basic mechanical skills and tools, this is a very manageable repair. The most important part is correctly identifying the module’s location on your specific vehicle and safely disconnecting the battery before you begin.
Is this part compatible with part number 20877116?
Yes, this module is a direct replacement for several part numbers, including 20877116, 20791901, 20850927, and 20827745. We program it to function identically to the original part specified for your VIN.
What causes these modules to fail?
Failure is often due to exposure to the elements. On trucks and SUVs where the FSCM is mounted on the frame rail, years of exposure to water, road salt, and vibration can cause corrosion and internal electronic failure. In other cases, internal components can simply wear out over time.
